T0 all rvhom it may concern.-

Be it known that I, GEORGE W. RICHARDS,

a citizen of the United States, residing at' Mountaintop, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Sectional Car-Wheels, of which the following is a specification.

This invention relates to a sectional carwheel, and has for its object to produce an article of this character in which the tread of the wheel is made in sections, so that when a portion becomes flattened or worn it can be very quickly remedied without incurring the expense of providing an entire new wheel.

Reference is to be had to the accompanying drawings, in which Figure 1 is a perspective view with one of the sections removed. Fig. 2 is a transverse sectional view. Fig. 3 is a detail perspective view. Fig. 4 is a transverse sectional view showing a modification.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 indicates the disk or body of the wheel, about which the various segments 2 are assembled. Any number of segments may be used; but the preferred number is six, as shown in the drawings. These segments 2 comprise the tread and flange of the wheel and extensions or flan es 3, which extend along one side of the dis 1, the inner ends of which fit around a raised seat 4 at the center of said disk. The disk 1 is adapted to fit against the shoulders 5, formedin the segments 2 where the extensions or flanges 3 meet the tread portions thereof. In the simpler construction the segments 2 are fastened to the disk 1 by means of bolts or rivets 6, passing through registering openings therein. A plate 7 is screwed upon a threaded extension 7 a integral with the seat portion 4 and is thus fastened to the raised seat 4 or may be made integral, if desired, and is of such a size as to overlap the ends of the extensions which fit against said raised seat. shown in Fig. 4, in which the edge of the disk 1 is beveled toward the outer side, and the shoulder 5 is rabbeted or undercut on its under side to interlock with the beveled edge of the 'body. When so constructed, it will be perfectly obvious that any lateral displacement of the tread of the wheel withrespect A modification of this structure is to the disk 1 will be impossible without first withdrawing it, so that the shoulder will not engage the beveled edge of the disk. Another modification (best seen in Fig. 4) consists in providing the plate 7 with an annular projection 8, which fits into corresponding recesses 9 in the portions of the segments which are adjacent the raised seat 4, affording interlocking connection between the plate 7 and said segments. When this construction is used in connection with the beveled edge of the disk, as heretofore described,

it will be'obvious that no bolts will be necessary to secure the segments in position, since the beveled edge prevents .their lateral displacement, and the interlocking projection 8 and recess 9 effectively prevent any radial movement.

When it is desired to remove one of the segments or to place one in position, it is simply necessary to remove the bolts 6, or, where the modified construction is used, to unscrew or loosen the plate 7 sufficient to break the locking connection between the projection 8 and the recess 9.

From the foregoing description it will be readily understood that by the use of my invention car-wheels maybe kept in perfect condition at avery slight cost, since when one side becomes worn or flattened, as is frequently the case, it will only be necessary to replace one of the segments, which will be very much cheaper and quicker than providing a whole newwheel, as has hitherto been the case.

Having thus described my invention, what I claim as new is' 1. A carwheel comprising a body, a sectional tread composed of a plurality of segments, each segment embodying an extension overlapping the body at one side thereof, a plate removably secured centrally of the side of the body upon which the extensions of the segments aforesaid are arranged, engaging the inner ends of the extensions to coact therewith to prevent displacement of the same, and means at the outer portion of the body of the wheel for fastening the outer portions of the segments thereto.

2. A car-wheel comprising a body and a sectional tread, the tread-sections having extensions overlapping the body, and a plate attached to the body and interlocking with the extensions aforesaid.

' 3. A sectional car-wheel comprising a body and a sectional tread, the tread-sections having shoulders interlocking with the outer edge ICC IIO

of said body, extensions projected from the tread-sections, and a plate removably attached to a side of the body centrally thereof and interlocking With the extensions of the tread-sections.

4. A car-wheel comprising a body, a sectional tread composed of a plurality of segments, each segment embodying an extension overlapping the body at one side thereof, a threaded extension projected from the central portion of the body, a plate secured to said extension, said plate being disposed at the side of the body upon which the extensions of the segments are arrangedand engaging the inner ends of said extensions to coact to prevent displacement thereof, and means at the outer portion of the body of the Wheel for fastening the outer portions of the segments thereto.

5. In a sectional car-Wheel, the combination of a disk having a raised seat on one side thereof, a sectional tread having a shoulder adapted to fit against the edge of said disk and having a flange extending along one face of the disk and bearing against the sides of said raised seat and having recesses therein, a

plate fitting over said raised seat and extending over said flanges and having a projection to engage in the before-mentioned recesses in the flanges to prevent radial movement of the sections, and means for securing the disk and tread-sections together.

6. In a sectional car-Wheel the combination of a disk having beveled edges and a raised seat on one side thereof, a sectional tread having a shoulder rabbeted or undercut upon its under side to receive the beveled edge of the disk to prevent lateral movement and also having a flange extending along one face of the disk and bearing against the sides of said raised seat and having recesses therein, and a plate fitting over said raised seat and extending over said flanges and having projections to engage the before-mentioned recesses in the'flanges to prevent radial movement of the sections.

In testimony whereof I affix my signature in presence of tWo witnesses.

GEORGE W. RICHARDS.
